Apotemnophilia, a disorder that blurs the distinction between neurology and psychiatry, is characterized by the intense and longstanding desire for amputation of a specific limb. Here we present evidence from two individuals suggestive that this condition, long thought to be entirely psychological in origin, actually has a neurological basis. We found heightened skin conductance response to pinprick below the desired line of amputation. We propose apotemnophilia arises from congenital… 

Apotemnophilia – the Neurological Basis of a ‘Psychological’ Disorder

TLDR
Functional brain imaging is shown to show that the unusual medical condition of apotemnophilia, in which otherwise mentally normal individuals express the strong and persistent desire for the amputation of a specific healthy limb, is caused by a failure to represent one or more limbs in the right SPL.

Apotemnophilia, body integrity identity disorder or xenomelia? Psychiatric and neurologic etiologies face each other

TLDR
This review summarizes the available studies of a rare condition in which individuals seek the amputation of a healthy limb or desire to be paraplegic, and proposes a multidisciplinary approach that comprises state-of-the-art technologies and a variety of theoretical models, including both body representation and psychological and sexual components.

TLDR
Proponents seek to have Potentemnophilia reclassified to a body identity integrity disorder such as gender identity disorder, in this way treatment modalities could be reassessed.

TLDR
More investigations are needed in this domain in order to develop noninvasive treatment strategies that approach this aspect of the patient’s distress within a globalist perspective.

Sexual and Food Preference in Apotemnophilia and Anorexia: Interactions between ‘Beliefs' and ‘Needs' Regulated by Two-Way Connections between Body Image and Limbic Structures

TLDR
It is postulate that sexual ‘aesthetic preference’ for certain body morphology is dictated in all individuals in part by the cortical representation of one's body image.

Potential relationship of self-injurious behavior to right temporo-parietal lesions

TLDR
Two patients with lesions of the right temporo-parietal junction presented to psychiatric inpatient services with SIB in the absence of notable neurologic deficits or suicidal ideation.

Xenomelia: Profile of a Man with Intense Desire to Amputate a Healthy Limb: This Case Report Helps Shed More Light on This Debilitating, Often Secretive Condition

TLDR
A case report helps shed more light on this debilitating, often secretive condition Xenomelia: Profile of a man with intense desire to amputate a healthy limb.

Xenomelia: a new right parietal lobe syndrome

TLDR
The authors propose that inadequate activation of the right SPL leads to the unnatural situation in which the sufferers can feel the limb in question being touched without it actually incorporating into their body image, with a resulting desire for amputation.

The findings in two cases show that self‐demand amputation (apotemnophilia) is related to erotization of the stump and to overachievement despite a handicap. The apotemnophiliac obsession represents

TLDR
The preliminary results suggest the existence of an extremely unusual clinically distinct condition characterized by a lifelong desire to have an amputation of a particular limb associated with serious negative consequences: amputation attempts, impairment and marked distress.

Amputees by choice: body integrity identity disorder and the ethics of amputation.

TLDR
It is argued that if patients are experiencing significant distress as a consequence of the rare psychological disorder named Body Integrity Identity Disorder, such operations might be permissible, and surgeons ought to be allowed to accede to their requests.

Cardiovascular effects of human insular cortex stimulation

TLDR
This work believes this to be the first demonstration of cardiovascular changes elicitable during insular stimulation in humans, and of lateralization of such responses for a cortical site, and may be of relevance in predicting the autonomie effects of stroke in humans and in the explanation of sudden unexpected epileptic death.
